Function
RTD/mA input
When the measured value exceeds either the Value maximum parameter or the Value
minimum parameter, the corresponding quality is set to "Out of range".

Deadband supervision

Deadband settings are used to select how sensitively RIO600 sends the updated
measurements to data subscriber over the GOOSE and Modbus communication. The
deadband settings must be sensitive enough to report events fast enough but also
insensitive enough not to load the Ethernet network with unnecessary events.
The deadband functionality decides the percentage change in the input values that
needs to be reported to the application. If the percentage change between the current
measured values and the last reported values is greater than the set DeadBand Value
(in %) of the measured range, the current measurement is reported to the application.
